This genus contains a single species^ a large Scijenoid of the California 

 coast, much resembling Aplodinotus f/runniens and having similar teeth, 

 except that the lower pharyngeals are separate, {roncador, gruuter, the 

 Spanish name, one of general application to these fishes, but on the Cali- 

 fornia coast used most particularly for the present genus.) 



1839. ROXCADOU STEAK\SI (Steindacliner). 



(Roncador.) 



Head 3i to 3|; depth 3 to 3i; eye 6 in head; snout 3^. D. X-I, 24; A. II, 

 8; scales 7-60-12. Body oblong, heavy forward; the back elevated anil 

 compressed; profile long, steep, and convex, abruptly rounded at the 

 snout; snout very blunt, al»ont equal to the interorbital space; mouth 

 moderate, low, subiuferior, the lower jaw included; maxillary 24, m head, 

 reaching at least to below middle of eye; preorbital nearly as broad as 

 eye; teeth in both jaws in broad villiform bands, none of them enlarged; 

 lower pharyngeals large, with many rounded molars, the outer series and 

 a patch at the outer corner, composed of villiform teeth; gill rakers 

 slender, rather short, lO-flG; posterior margin of preopercle with short, 

 stout teeth; dorsal spines strong, the longest 2 in head; caudal lunate, 

 the upper lobe the longer; second anal spine stout, 3^ in head; pectorals 

 much longer than veutrals, about as long as head; scales below lateral 

 line in slightly oblique series. Color grayish silvery, with bluish luster, 

 some streaks of dark points along the rows of scales; breast and belly 

 with two dusky longitudinal streaks; a very conspicuous jet-black spot 

 as large as eye at base of pectoral; axil and lining of gill cavity black. 



* The. nominal species, called Corvina jacobi, described from yoting specimens taken at 

 San Diego, is doubtless identical with Corvina saturna. The' only diti'erence indicated 

 by Steindacliiirr wliicli cnuld have any serious importance is in the coloration, in the 

 species oi Hcfniuhin. A iilsotremus, and other analogous groups the young often have 

 exactly the coloration assigned to Corvina jacobi, while the adult may be very differently 

 marked. We have not seen the very young of saturna, but have no doubt tiiat it passes 

 through the ''jacobi" coloration in the course of its development. 

 The following is the sub.stance of Dr. Steindachner .s description : 



Head 3; depth 3. D. X-I, 27: A. II, 8; scales 11-56-16. Body moderately elevated; 

 mouth moderate, rather inferior; maxillary reaching middle of eye; outer rows of teetli 

 in each jaw slender, somewhat enlarged, those in the upper jaw much larger than in 

 lower; preopeicle finely serrate. Dorsal sjiines very slender, the fourth J- length of 

 bead, higher llnni tlie si^ff r:i\s: seinnd anal sjiine more than twice as strong as dorsal 



spine.s, as lung as IV ini.ldle ,,i"i \ c lo , ilge of oiicrcle, lower than the soft rays. Caudal 



truncate oi- sliulitly ii>ii<a\'e: iiecioials slmrlir Ihaii ventrals, the first ray of the latter 

 being lilamentdiis.' Scales (in liody and liead ctenoid. Silvery gray, darker above; 3 

 dark l)r(i\v]i l(ni.i:itudinal stiipos along .sides, the lower broadest, extending from eye to 

 middle of eaiulal, the middle one running to up])er ed-e i.f tail, the ni)]ier to soft dorsal; 

 below these Btri|ies are sunietiiues feebler ones, besides hrownish lines iollowing the rows 

 of seales; tins plain, nu)re or less punctulate; markings probalily les.s di.stinct in theadult.
